this book was really good. The whole series is addicting. As soon as I put one down, I have to pick another one up. Thsi one in particular was really good. But it was disapointing for the sudden switch in character for Nate.But it's very exciting that S and B are friends again. I knew it couldn't have gone on forever. All-around, it was very good and if you liked the first two books of this series, this one is better.
